Pin point oil leak

I have a 1999 Ford Taures 3.0 V-6 with 86,000miles. It just started to leak oil and it looks like its leaking above and around the crank shaft. Its not really bad yet and leaks more when its shut down. My Guestion is could it be anything above the crank shaft that could leak oil.maybe like a preasure oil line that i cant see.I power washed it and took of the plastic inside fender so i can see better and still cant tell where its coming from besibes running oil on the sides and right above the crank shaft.Please help me minus out the posiabilties of anything eles that it could be besides the crank shaft inner seal.Thanks
